My tetras have risen from the dead…

[Freyfish]

I did a water change yesterday and did a small shuffle around of my wood and plants. I’ve just fed the fish and realised I now have 8 neon tetras (had 6 left after 3 deaths). One I found and two I never did so I assumed they had been eaten or just gone into a little crack somewhere. This was about a month ago so they were obviously
stuck somewhere. Has anyone else had a fish disappear and then reappear weeks later? Just as a PS they look perfectly fine and happy!

Had 2 babies Mollies a couple of weeks ago but hadn't seen them till this morning when i found them in the filter

Yes, often.

Small tetras are very good at doing that, but I've had larger fish do it as well.....

I tend to loose a couple emperors for a few days and then they pop up out of the plants like nothings happened!
